EUGENE SMITH, OF SAN FRANCISCO, CALIFORNIA.

BELT-HINGE.

SPECIFICATION forming part of Letters Patent No. 294,923, dated March 11, 1884.

To all whom, it may concern.-

Be it known that I, EUGENE SMITH, of the city and county of San Francisco, and State of California, have invented an Improvement in Belt-Hinges54 and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a hinge for uniting the ends of belts; and it consists of the combination of devices hereinafter shown 'and claimed.

It also consists in cert-ain details of construction, all of which will be more fully explained by reference to 'the accompanying drawings, in which* Figure 1 is a perspective view of my hinge.

Fig. 2 shows its application to a belt. Fig. 3

is a transverse section.

b This invention is designed toV unite the meeting ends of belts in a better and more durable manner than by lacing, and at the same time to protect the belt from cracking or chang as it passes over pulleys.

A A are the two meeting ends of a belt. B B are thin steel plates, which are of a width equal to that of the belt, and of such a length as to allow them to be folded over 'the ends of the belts and be riveted upon them. The bent edges C of these metal plates are cut out like av hinge, so as to fit together and be held in place by a pin, D, which is riveted at both ends. Sufficient playin the joint is provided to allow the pin to be' removed at will. The edges ofthe plates, which are 'onthe inside ofthe belt and next to the pulley, are shorter than the outside edges, and do not extend as far beyond the rivet-holes a, which pass through The outside portions of the plates have extensions b with rivet-holes f, which pass only through them and the belt. These extensions prevent the chang or cut- Application filed December 27, 1883.' (Nomodel.)

[ting of the belt upon the opposite or inner side as it passes over the pulleys, and also protects it upon the opposite side whenever it The rivet-holes are punched through the steel plates, so as to form a burr upon the inside.

These burrs extend into the belt a short distance, and thus protect the belt lfrom the chafing action of the rivets, and the rivet from the chaiing action of the hinge, and also help to prevent the tearing of the leather.

If thehinges are required for belts which run over very small pulleys, the projecting portion in which the rivet-holes are made may be left off and the rivet-holes made straight across, thus shortening the hinge, so that it willreadily conform to `the curve of the pulley. The ends of the hinge are also bent or beveled from the inner edges next the belt outward, so as to relieve the belt from any chaiing action of the hinge. Those portions of the hinge which lie against the-belt are indented or roughened, so as to increase the grip or hold upon the leather when the rivets are headed up.

- Having thus-described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The plates B B, having their bent edges C C cutout like a hinge, so as to t together, andprovided with the rivet-holes a, and extensionsb, having the rivet-holesf, in combination with the pin D, substantially as and for the purpose herein described.

In witness whereof I have hereunto set my hand.
